Tinnitus of TMJ origin: a preliminary report.

Twenty patients whose chief complaint was tinnitus were examined. They were not known to have temporomandibular disorders. They did not have pain or dysfunction. They were examined by physicians for ear disorders and the results were considered negative. Each of these patients had a complete history and clinical temporomandibular joint examination. The clinical examination included muscle and joint palpation and stethoscopic examination of the joint. This examination also included selected computerized mandibular scans and electromyographic studies of selected facial muscles. Each subject had eight views of transcranial lateral oblique x-rays taken. It was determined that 19 of these individuals had one or more clinical, electromyographic, and radiographic indications of a temporomandibular disorder. From this study, it appears that individuals who have tinnitus with no apparent otologic basis for this symptom should have a careful evaluation of the temporomandibular apparatus. A temporomandibular disorder may be one of the primary causes of this symptom.

Development of alloplastic materials for temporomandibular joint prosthesis: a historical perspective with clinical illustrations.

This paper gives the history of the development of alloplastic materials presently used in the temporomandibular joint (TMJ). It discusses the evaluation of TMJ implants, from those being used primarily for ankylosis to the more varied and sophisticated implant designs used today. There is a discussion on the treatment of osteoarthritis with implants and also a discussion on the use of TMJ implants to repair skeletal and dental malrelationships, primarily anterior open bites. Included is a presentation of the latest research by Schellhas et al., which establishes that previously undiagnosed organic disease in the joint proper is a common cause of skeletal and dental malrelationships and that TMJ disease can cause malocclusion.

Limited impact of testicular self-examination promotion.

Analysis of data obtained through a survey of 415 men in New Orleans, Louisiana, and Rochester, New York, indicates that the transfer of testicular self-examination (TSE) skills from the medical community to the public has been relatively ineffective. Only two of every 100 respondents reported monthly self-examination performed at the correct time and with the proper method. The findings suggest that, until the transfer of self-detection skills is improved, one cannot assess the efficacy of the technology itself. Problems impeding such improvement are reviewed.

Minority health status in New Jersey.

The health status of minorities in New Jersey, like that of the nation, continues to lag far behind that of whites. In an effort to address this problem, UMDNJ has established a Minority Health Institute to focus the resources of the state's academic health science center on the problem.

A comparison of graphical nomogram methods with a computerized Bayesian analysis method in the interpretation of serum phenytoin concentrations.

A study was performed to compare the predictability of a reported Bayesian graphical method, the drug nomogram used in the Bayesian Computer Method and the Driessen Nomogram with that of a computerized Bayesian analysis method in the interpretation of serum phenytoin concentrations. It was found that the results generated by the graphical method were similar to those of the computer with a mean prediction error of 3.9 mg/day in the dose to achieve a concentration at steady-state of 20 ml/l. Overall the results of the graphical method were less biased and had more precision with a significant improvement in relative precision (P less than 0.01) than the initial estimate or Driessen methods.

Clinical evaluation of TMJ arthroplasties with insertion of articular eminence prosthesis on ninety patients (an eight year study).

This paper represents an analysis, accomplished over an eight-year period, of 90 individuals who have been operated on for various arthritic diseases of their temporomandibular joints (TMJ). In arthritic changes of the joint, several changes may occur: perforation of the disc, flattening of the articular eminence, asymmetrical condylar movement, and chronic synovitis. This may result in increased synovial pressure on nerve fibers within the capsule of the joint, and a variety of referred pain symptoms. Prior to operation, a careful differential diagnosis was made by an otolaryngologist and, frequently, by a neurologist/neurosurgeon and a psychologist. The prosthesis inserted during surgery was a metallic device which fits over the articular eminence in the upper portion of the joint. This prosthesis accomplished primarily three functions: elimination of the crepitus; restoration of the contour of the eminence; separation of the articular surface of the joint.

Surgical correction of temporomandibular joint arthritis.

Restoration of the contour of the articular eminence with a prosthesis has been successful when chronic sublaxation has resulted from flattening of the eminence. Use of a prosthesis is helpful in the treatment of patients with arthritic disease of the temporomandibular joint. A careful differential diagnosis is necessary to eliminate other possible causes of the patient's symptoms.
